Abstract (en)
[origin: US2019377356A1] A navigation system for an automated guided vehicle comprises a set of marking elements which are to be arranged in grid form on the floor and in which navigation information is encoded; a sensor device to be arranged at the automated guided vehicle for reading navigation data from the marking elements; and an evaluation device connected to the sensor device for generating control signals for the automated guided vehicle with reference to read navigation data. Each of the marking elements has at least two graphical code patterns that are each designed as one-dimensional code patterns and comprise a code applied along a scanning direction, with the scanning directions of the at least two graphical code patterns being aligned offset from one another by an angular offset.
Abstract (de)
Ein Navigationssystem für ein fahrerloses Transportfahrzeug umfasst einen Satz von rasterartig am Boden anzuordnenden Markierungselementen, in denen Navigationsinformationen codiert sind, eine am fahrerlosen Transportfahrzeug anzuordnende Sensoreinrichtung zum Auslesen von Navigationsinformationen aus den Markierungselementen und eine mit der Sensoreinrichtung in Verbindung stehende Auswerteeinrichtung zum Erzeugen von Steuerungssignalen für das fahrerlose Transportfahrzeug anhand von ausgelesenen Navigationsinformationen. Jedes der Markierungselemente weist wenigstens zwei graphische Codemuster auf, die jeweils als eindimensionale Codemuster ausgeführt sind und einen entlang einer Abtastrichtung aufgetragenen Code umfassen, wobei die Abtastrichtungen der wenigstens zwei graphischen Codemuster um einen Winkelversatz zueinander versetzt ausgerichtet sind.
